Re:Build your own bare-metal ARM cluster

I'm really grateful to Alex Ellis for his gist[0] to install kubernetes on RPis. I built my own 4 nodes cluster following this gist. It's been great to get my hands dirty with kubernetes
That being said, I had to buy an Asus Tinkerboard with 2GB RAM to serve as the cluster master because 1GB RAM was a bit short. My master node went below 100MB of free RAM and pod evictions (of kube-system pods) started to happen. If I were to do it again, I think I would use only Tinkerboards just for the convenience of having the same OS/hardware on each node.
